Design Criteria for Optimum Cooling and Shielding of Enclosures
of the design should be to use conductive material, limit the number and size of openings and eliminating seams to the extent possible. Achieving these objectives, however, is often in conflict with cooling, maintainability and cost. The challenges of the electronic packaging engineer are many...

for cooling airflow) or NEMA 12 (sealed, dust-tight enclosure). NEMA-1 drives are susceptible to dust contamination. Dust on hardware can restrict airflow, degrading performance from heat sinks and circulating fans. Dust on electronic devices can cause malfunction or failure. Dust absorbs moisture...

Air movers and coolers
. When a fan is required for enclosure cooling, a washable air filter at the incoming air stream is recommended. When using air filters, a plenum must also be used to separate the fan from the filter and to maintain even, effective airflow. If a plenum is not used, the filter is placed against the fan...

Hot tips for cool enclosures
When it comes to cooling enclosures, it's time to think inside the box. Filter fans are best for applications with relatively clean ambient air and ambient temperatures lower than the desired internal enclosure temperature. They are generally available in sizes from 12 to 680 cfm. Air-to-air heat...
